The Haflaah explains the meaning of when learning from a rebbi, we should see him as an angel of Hashem. An angel is stationary. Similarly, a rebbi should set aside his own edification for the benefit of thr talmidim. The Chasam Sofer explains that the moon agreed to be made smaller, so that the stars could be seen.
